food safety / 10 facts on food safety
« on: August 08, 2018, 09:10:56 PM »
The great majority of people will experience a foodborne disease at some point in their lives. This highlights the importance of making sure the food we eat is not contaminated with potentially harmful bacteria, parasites, viruses, toxins and chemicals.

Food can become contaminated at any point during production, distribution and preparation. Everyone along the production chain, from producer to consumer, has a role to play to ensure the food we eat does not cause diseases.

Fact 1: More than 200 diseases are spread through food.
1 in 10 people fall ill every year from eating contaminated food, and 420 000 people die each year as a result. Children under 5 years of age are at particularly high risk, with some 125 000 young children dying from foodborne diseases every year. Proper food preparation can prevent most foodborne diseases.

Fact 2: Contaminated food can cause long-term health problems.
The most common symptoms of foodborne disease are stomach pains, vomiting and diarrhoea. Food contaminated with heavy metals or with naturally occurring toxins can also cause long-term health problems including cancer and neurological disorders.

Fact 3: Foodborne diseases affect vulnerable people harder than other groups
Infections caused by contaminated food have a much higher impact on populations with poor or fragile health status and can easily lead to serious illness and death. For infants, pregnant women, the sick and the elderly, the consequences of foodborne disease are usually more severe and may be fatal.Fact 4: There are many opportunities for food contamination to take place
Today’s food supply is complex and involves a range of different stages including on-farm production, slaughtering or harvesting, processing, storage, transport and distribution before the food reaches the consumers.

Fact 5: Globalization makes food safety more complex and essential
Globalization of food production and trade is making the food chain longer and complicates foodborne disease outbreak investigation and product recall in case of emergency.

Fact 6: Food safety is multisectoral and multidisciplinary
To improve food safety, a multitude of different professionals are working together, making use of the best available science and technologies. Different governmental departments and agencies, encompassing public health, agriculture, education and trade, need to collaborate and communicate with each other and engage with the civil society including consumer groups.

Fact 7: Food contamination also affects the economy and society as a whole
Food contamination has far reaching effects beyond direct public health consequences – it undermines food exports, tourism, livelihoods of food handlers and economic development, both in developed and developing countries.

Fact 8: Some harmful bacteria are becoming resistant to drug treatments
Antimicrobial resistance is a growing global health concern. Overuse and misuse of antimicrobials in agriculture and animal husbandry, in addition to human clinical uses, is one of the factors leading to the emergence and spread of antimicrobial resistance. Antimicrobial-resistant bacteria in animals may be transmitted to humans via food.

Fact 9: Everybody has a role to play in keeping food safe
Food safety is a shared responsibility between governments, industry, producers, academia, and consumers. Everyone has a role to play. Achieving food safety is a multi-sectoral effort requiring expertise from a range of different disciplines – toxicology, microbiology, parasitology, nutrition, health economics, and human and veterinary medicine. Local communities, women’s groups and school education also play an important role.

Fact 10: Consumers must be well informed on food safety practices
People should make informed and wise food choices and adopt adequate behaviors. They should know common food hazards and how to handle food safely, using the information provided in food labelling.

The major difference between soybean and olive oil lies between their fat types; i.e. Soybean oil contains polyunsaturated fats; while Olive oil contains monounsaturated fats.
Almost all oils are obtained from some types of plant sources; while the oil categories contain different types of fats, according to which they differ and are uniquely identified. Consequently, Soybean oil is one of the types of vegetable oil; while Olive oil which is a fat is obtained from olive seeds. In today's world, Oils are making trends in the cooking and baking fields. They play the most essential ingredients role in many sectors; oils like soybean and olive are used in other fields like cosmetic and are applicable in the health related issues. These oils at some stage are recommended by the dieticians or physicists, in order to maintain a healthy and happy life.Soybean oil is most beneficial for baking, frying, cooking and salad dressings. The oil is obtained from the well known and cultivated soybean seeds; which are considered to be the rich source of proteins. The oil is rich in oxidation-prone linolenic acid; poly- and monounsaturated fats; low in saturated fats and trans fat-free; along with these compositions the oil is also a rich source of proteins.

Soybean oil is processed to form drying oil, which is further used in the applications of printing inks (soy ink) and oil paints. Other than cooking, the oil has tremendous number of decorating applications in mayonnaise, salad dressings, frozen foods, imitation dairy and meat products and commercially baked goods like margarine. Along with these the oil can also be used in shortening purposes in the old-fashioned pie crust or blended with a flavored vinegar for a new dressing, as the oil’s natural flavor gets adapted to the one in which it is used.
Olive oils are known for their rich and extra healthy benefits. From traditional times, olive oils are extracted from the olive seeds. The oil has unique types; they are categorized according to their extraction types into:
Extra Virgin olive oil- comes from the first pressing of the olives;
Virgin Olive oil - oil does not undergo any refinement;
Olive oil - it’s a blend of virgin olive oil and lower-quality refined olive oil
Olive Pomace oil - this is very refined olive oil, obtained from the residue that remains once the oil is pressed
Among the all above, the extra-virgin oil is regarded to be the best of all, sue to nits healthier cooking benefits.

The olive oils have applications in cosmetics, pharmaceuticals, soaps and also it act as a fuel for traditional oil lamps. Olive oils and their types are of particular flavor texture and shelf-life makes them more useful in different applications like, human direct consumption on bread, or salads; also applicable in the indirect consumption in domestic cooking and catering, along with the industrial uses such as animal feed or engineering. 

In comparison factors, soybean oil is one such type of oil which has a mild flavor and is easily applicable in the cooking fields; whereas olive oils and their categories are available in different flavors and features, hence, these are applicable according to their uses in the relevant fields. Both oils are obtained from plant sources, and both are liquid at room temperatures, but they have a major difference in the health related issues; i.e. soybean oil possessing polyunsaturated fats are known to lower down the total blood cholesterol level; whereas olive oils which posses the monounsaturated type of fats are known to lower the LDL (Lousy) Blood cholesterol level.

In regrds to health benefits, soyabean oil is being used as nutritional Supplement in Intravenous Feedings and has an
established role in the treatment of patients suffering from Alzheimer's Disease.
Olive OIL on the other hand has the following benefits:
-Reduce Breast Cancer Risk
-Maintain Healthy Cholesterol Levels
-Extra Virgin Olive Oil protects against Alzheimer's Disease
-Helps Prevent Acute Pancreatitis
-Protects the Liver
-Protects from Ulcerative Colitis
-Helps Prevent Stroke

Nutrition and Food Engineering / what is flaxseed?
« on: April 30, 2018, 12:10:29 PM »
Flaxseeds have been consumed for at least 6,000 years, making them one of the world’s first cultivated superfoods. What does flaxseed do for you that makes it one of the most popular “superfoods”? Flaxseeds contain anti-inflammatory omega-3 fatty acids (although not the same type that fish, such as salmon, do) along with antioxidant substances called lignans that help promote hormonal balance in addition to several other benefits of flaxseed.
Flaxseeds, sometimes called linseeds, are small, brown, tan or golden-colored seeds. In fact, linseed or “flax seed” are different names for the same seed. Flaxseeds are a great source of dietary fiber; minerals like manganese, thiamine and magnesium; and plant-based protein.

Flax is one of the richest sources of plant-based omega-3 fatty acids, called alpha-linolenic acid (or ALA), in the world. Another unique fact about flaxseeds is that they are the No. 1 source of lignans in the human diets; flaxseed contain about seven times as many lignans as the closest runner-up, sesame seeds.
Flaxseeds can be eaten as whole/unground seeds but are even more beneficial when sprouted and ground into flaxseed meal. Grinding flax helps you absorb both types of fiber it contains, along you to take advantage of even more of the benefits of flaxseed.Whole flaxseeds will pass right through your body without being digested, which means you will not receive many of the inherent benefits!

Additionally, flaxseeds are used to make flaxseed oil, which is easily digested and a concentrated source of healthy fats. Below you’ll find more about how to sprout and grind your own flaxseed, plus ideas for using all types of flax in recipes.
